Publication number: 20070054015Abstract: The present invention concerns a method and an apparatus for filling of preferably high-viscous ice cream into receptacles, comprising supplying a substantially constant flow of ice cream to a filling apparatus, which in a flow channel leads to an outlet for successive filling of the receptacles, reducing the flow volume of the flow channel during filling of a receptacle with the outflowing ice cream by means of telescopic displacement of two tube sections, which forms the flow channel, cutting the ice cream hanging out, when the filling of the given receptacle has ended, and subsequently increasing the flow volume, while the subsequent receptacle is being positioned relative to the outlet for filling. Thus a controlled acceleration and outflow velocity of the ice cream is achieved, whereby filling of high-viscous ice cream can be performed rapidly and with significant geometrical accuracy.Type: ApplicationFiled: September 14, 2004Publication date: March 8, 2007Applicant: TETRA PAK HOYER A/SInventor: Ejvind Waldstrøm

Publication number: 20040187708Abstract: There is provided a method and an apparatus for forming and filling a predetermined amount of ice cream having a high viscosity to a carrier element for the ice cream, where a bar of ice cream is extruded out of a supply tube and is formed in correspondence with the carrier element in a forming equipment by a pressing between at least two form parts and simultaneously providing a breakage point in the ice cream bar at the inlet to the forming equipment, whereafter the forming equipment is opened and the ice portion, which is formed thereby at the end of the ice cream bar is transferred directly to the carrier element, whereafter the ice cream bar is broken at the breakage point. Hereby, a process for forming and filling a predetermined amount of rigid ice cream to a carrier is achieved with the possibility of reducing or even eliminating a subsequent cooling before the ice products are transported to a cool storage.Type: ApplicationFiled: May 12, 2004Publication date: September 30, 2004Inventor: Ejvind Waldstrom

Patent number: 5212960Abstract: A method and system for producing extruded edible ice products wherein an extruded string is conveyed unbroken through a continuous freezing zone, with only constrictions or notches being provided in the string by transversely movable tools while the ice substance is still formable. After a hard freezing of the extruded string, single bodies are separated from the extruded string by a simple successive breaking action on a front end of the string, and a desired distance between individual severed bodies can be produced by permitting the bodies to fall onto a conveyor moving at a speed which is higher than a conveying speed of the extruded string.Type: GrantFiled: January 7, 1992Date of Patent: May 25, 1993Assignee: O.G. Hoyer A/SInventor: Ejvind Waldstrom

Patent number: 4548573Abstract: Frozen confection articles are produced in non-enveloped, openable moulds by subjecting the closed moulds to an innoxious freezing medium such as very cold air. An apparatus for producing such frozen or moulded articles comprises a plurality of parallel, endless rows of moulds moving along a closed path of straightlined and curved configurations, these moulds each consisting of opposed, mutually hinged mould parts, which are forced together during motion along the straightlined parts of said path, as corresponding to setting or freezing zones, while the moulds are openable for discharging of the hardened or frozen products as they are guided along the curved path, in which the moulds diverge from each other and thus provide space for the opening thereof.Type: GrantFiled: November 4, 1983Date of Patent: October 22, 1985Assignee: O. G. Hoyer A/SInventor: Ejvind Waldstrom

Patent number: 4489536Abstract: From a row of objects which are conveyed on an intermittently movable feeding conveyor, every second object is deposited on lines of wrapping materials at a first station, which lines are advanced continuously under the feeding conveyor, and the remaining objects are deposited on the same lines of wrapping materials at a following station. In connection with one or both depositing steps. the objects are shifted transversely of the direction in which said lines are advanced. Thus, the number of lines of wrapping material is only half the number of objects in each row, whereas the distance between the lines will be increased so much that the lines may be sealed lengthwise and crosswise by means of rotating sealing means.Type: GrantFiled: September 30, 1982Date of Patent: December 25, 1984Assignee: O. G. Hoyer A/SInventors: Kaj Degn, Ejvind Waldstrom

Patent number: 4417610Abstract: A system for dispensing a viscid medium from a supply medium flow to a number of receptacles, with the system including a filling station and a distributor having an inlet for a pressurized supply medium flow and a number of outlets individually connected to a series of dispenser openings located in the filling station. A support is provided for sequentially moving consecutive groups of receptacles through the filling station to align a single receptacle of each group with the respective dispenser openings. An outlet valve arrangement is located in a path of the medium flow upstream of the dispenser openings. A valve control is operable to repeatingly open and close the outlet valve arrangement to allow concurrent medium outlet from the dispenser openings during an opening time interval corresponding to a predetermined medium volume being dispensed for a required filling of the receptacles of the respective consecutive groups.Type: GrantFiled: March 31, 1981Date of Patent: November 29, 1983Assignee: O.G. Hoyer A/SInventors: Ejvind Waldstrom, Gerhard Kaufmann

Patent number: 4413461Abstract: Ice cream lollies of complex shapes are produced by a die pressing operation, whereby a prefrozen and deformable lolly body is placed between a pair of die tools. The bodies to be die shaped may be either conventionally produced bodies as prefrozen about a stick, in which the body is held during the shaping operation, or they may be lumps of extruded prefrozen material, whereby a preparatory conventional mold freezing can be avoided. The die tools may be used additionally for concurrently providing and sealing an envelope about the final product, thus finishing it as a sales product.Type: GrantFiled: July 20, 1981Date of Patent: November 8, 1983Assignee: O. G. Hoyer A/SInventor: Ejvind Waldstrom

Patent number: 4192415Abstract: Apparatus for receiving frozen confections supplied in a single row on a supply conveyor and delivering the confections to a discharge conveyor located at a lower level. The supply conveyor overlaps a rotary turret and a movable stop provided above the turret halts every second confection arriving on the supply conveyor following which a carrier on a movable chain pushes the confections along a transverse chute down onto the discharge conveyor. The remaining confections are allowed to travel through 180.degree. on the turret following which they are halted by a stationary stop. Carriers on a second movable chain then push each of the latter confections along a second transverse chute onto the discharge conveyor in a space between two confections delivered via the first chute and with reversed orientation. The discharge conveyor, the carrier chains and the turret move continuously and in synchronism.Type: GrantFiled: April 4, 1978Date of Patent: March 11, 1980Assignee: O.G. Hoyer A/SInventors: Ole G. Krener, Ejvind Waldstrom
